a right, or is it simply not illegal? here in America you don't have to have a right to do something for it to not be illegal.
plan to, or are in the process of destroying? I would say if you are in the act of destroying it, and I can take it without breaking a law, trespassing, assault, breaking & entering etc, I don't see how its a crime.
do you think we have to Michael Scott declare something to justify the stopping of a crime? would it have helped in your opinion if he had listed the statutes first that were being broken?
I think if the cops, fire department, or especially in this case security, could have done the same action without question it shouldn't be a question if him doing it is illegal. imo either of those other three groups could have done the same thing, no problem. that is part of why I brought up that I didn't know if it was home or away. If someone is burning something on/in my employers property in a manner that is going to damage private property, even to a small degree, I don't think I would face any punishment if I took action to stop that act. even if I am not specifically employed to handle that situation. In this case the act would have likely inhibited his ability to work; and their rights of protesting ended the moment they stepped on private property. especially non-violent acts. I might feel different if someone told me he punched the protesters or kicked them into the fire to take the flag away.
